Have you seen this movie? With respect to socionics, people usually find their type and remain relatively satisfied that it accurately describes them. There are some people, however, that seem to exhibit various types at various times or in various situations - I think it's somewhat analogous to the people who do not fit into the predefined, particular roles in the movie. Personally, I cannot conclude that I'm any certain type, or even any certain quadra, and I'm wondering how many others cannot find a type to call "home" in socionics.
I also wonder how many folks find a type - then associate it to their self-identity in such a manner that it becomes prohibitive to their desire to grow in "weak areas" and become conditioned.
Do you think that people can have "Divergent" personalities which are able to interchange functions depending on intrapersonal/interpersonal/extrapersonal variables?
